Bug Fixes

  • SVG children API — JSX children auto-serialized to SVG content
  • SVG opacity support — opacity, fill-opacity, stroke-opacity via ExtGState with inheritance through <g> groups
  • Page style prop inheritance — <Page style={{...}}> now properly resolves styles through serializePage and the layout engine
  • WASM time panic fix — certify and redact in browser WASM no longer crash due to SystemTime unavailability
  • PKCS#1 auto-conversion — PKCS#1 RSA private keys automatically converted to PKCS#8 format
